MRI in the Common Headache Population

The purpose of imaging in the clinical context of common headache presentations is to exclude an underlying lesion that may be causing the phenotype. There are two groups of relevant studies; the first investigate patients that have presented due to headache, more pertinent to the clinical decision of whether to image, but typically weakened by opaque patient selection as well as the use of both CT and MRI modalities. This is possibly a reflection of changing practice, and is certainly indicative of the increased availability of MRI over the past two decades. The proportion of structural lesions in this population informs the utility of imaging in clinic practice. Since the decision to image hinges upon this likelihood, some detail will be presented. The second group is represented by population-based studies of imaging in migraine. The findings of 'infarct-like' changes on MRI uncovered in these investigations will be discussed, and their implications considered.
